Adaptive Neuroplastic Responses in Early and Late Hemispherectomized Monkeys

Figure 2

Perimetry: infant-lesioned monkeys (a) were able to detect visual stimuli at 45° in the “blind” hemifield, whereas no visual response could be elicited in the adult-lesioned subjects (b) in the contralateral hemifield. Normal-sighted monkeys had a 75% visual perimetry at 90° in both hemifields (c) (adapted from [13]).
